Gathering shit samples for medical analysis

An incredible way of gathering his feces samples was exposed by this nasty boy, whose ass has taken over his mind. With his anus full of shit, collected for several days, he’s squatting above the large crystal bowl and starts crapping right into it, filling it to the brim in a minute. He didn’t even have to spread his ass with his hands, because the huge pressure of shit has made it instead of him. A fat brown snake has crawled out of his anus, making it swell while he’s shitting. The flawlessly white sheets on his bed just stress the extreme action happening in this shitting video, where the guy has supplied medics with feces for a year.
